CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent 'No. 231,666, dated August31, 1880.

Application filed July 23,1880. (No model.)

To all whom it may concern Be it known that I, EMIL HEINTZ, of Auburn,in the county of Cayuga and State of New York, have invented a new anduseful Carpet-Stretching Device, of which the following is aspecification, reference being had to the accompanying drawings, inwhich simi lar letters refer to like parts, and of which- Figure l is aperspective view; Fig. 2, a side elevation Fig. 3, an end elevation ofthe U-piece D and. Fig. 4, an end elevation of the U-piece G, with itshinge F.

My invention relates to that class of carpetstretchers which areadjustable, and which may be made to adapt themselves to such lengths aswill meet the requirements of various-sized rooms or apartments.

The object of the invention is to construct a carpet-stretcher which,while being of the adjustable type, will require but a single operatorfor stretching and nailing down of carpets, and which may be locked inits place after stretching of the carpet, and thus remain at the will ofthe operator.

These objects are attained by the mechanism illustrated in the drawingsalready described, and are accomplished by means of two bars, G and K,of any desired length, a pivoted U- piece or lock-clutch, D, a similarU-piece in a reversed position, G, and a foot provided with a gang ofteeth pitching forward, as shown at O, the teeth being represented bythe letters P P P, and adapted for biting into and grip ing the carpetfabric without a possibility of slipping or tearing the same.

A is a hinged heel for abutting against the base-boards of the room, andis connected with the bar 0 by means of a hinge, B. G is the primal orbase-board bar, and is provided at any required distance from its footend with the U-piece D, and at the opposite end with a hinge, F, placedin a position reversed to that of the'hinge B. D is a U-pieee pivoted toO at E, as required. E is the pivot upon which the clutch or U-piece Dworks. F is a hinge connecting the bar 0 with the U-piece G. G is theU-piece, which is connected with G by the hinge F, and acts as a guideto the bar K. K is a lengthening-bar, provided with a series of H. J isa removable pin,by means of which the lengthening-bar K may be securedat any desired length by passing the pin through the holes H and thelimbs of the U-piece G. L is a strip screwed into the lengthening-bar Kby means of screws R R, and .serves to carry the stretcher-foot 0. N isa pair of hangers secured to the piece L, and swinging freely thereon bymeans of the pivot M. These hangers are securely fastened to thestretcher-foot O. O is the stretcher-foot, provided underneath with aseries or gang of griping-points, P, at regular intervals, and securedto O by means of the corresponding piece Q. I

Having thus set forth the various parts of my invention, I will endeavorto (lescribeits operation: I adjust my device to any desired lengthrequired for its most efficient work by means of the pin J, acting asdescribed. I now bend over toward the hinged heel A the U-piece D, andthus release the end of the lengthening-bar K. I then place the heel Aagainst the base-board of the room, and the stretcher-foot O in itsproper position upon the carpet to be stretched. I now lift upward uponthe stretcher, and the bars 0 and K, acting upon the hinge F, cause thestretcher-foot O to follow, together with its attachments. When I havethus attained a sufficient takeup I simply press down upon the bar K,which act causes the stretcher-foot to gripe into and carry or stretchthe carpetin itsforward movement, which, when completed, I there secureby pressing the U-piece back over the end of the bar K. Thus it will beseen that I retain, by my device, the carpet in a stretched conditionfor ready and convenient nailing down.

Having thus described my invention, what I desire to secure by LettersPatent, and what I claim, is-- The two U-pieces D and G, the two hingesB and F, and the pivoted piece N, in combination witlrthe bars 0 and K,pivoted as at E J, the bar K having adjusting-holes H, the wholeconstructed substantially as set forth, and for the purpose described.

EMIL HEINTZ.
